The Premier League campaign may have only just finished but already plenty of clubs are looking to strengthen their squads for next season while letting plenty of players go.

At Tottenham Hotspur, boss Mauricio Pochettino wants his club to spend cleverly in the transfer market while speculation continues to grow around a potential exit from the north Londoners for Kyle Walker.

Arsenal are looking to keep star Alexis Sanchez as well as add more quality to their ranks, while Chelsea are being linked with plenty of high profile arrivals and departures.

West Ham boss Slaven Bilic said this week that he wants to add 'game-changers' to his squad this summer.

"I hope I can give you good moments"

The Argentine defender has joined on a free transfer having left Manchester City after nine successful years.

Here’s what he had to say:

This is an absolute pleasure to be part of West Ham United Football Club. I hope I can give you good moments.

Of course, I come to the Club to enjoy myself and hopefully we can have a very successful time.

I thought I wanted to keep playing in the Premier League.

For me, after being in this country for so long, this is a new challenge for me in the Premier League and I’m ready for it and looking forward to it.

West Ham sign Zabelata

Everyone knew it was happening - but it’s now been confirmed.

Well, sort of anyway - even if West Ham haven’t yet said anything. That will happen at 1pm.

But Zabaleta is now a Hammer.

City are reportedly close to tying up a deal for Monaco’s Benjamin Mendy as well as his team mate Silva.

David Luiz

The Brazilian centre back has been excellent this season, but there were some doubts when Chelsea re-signed him - not least from the man himself.

He said: “I was winning in Paris. I went to Paris for two years and won all the titles in France. I had a great life, I had a great credibility with the club.

“I had everything in Paris and then I took a risk to come back to a country that was not that happy with me. They always criticise me a lot even with the Champions League, Europa League and playing all the games. That’s why it was a risk and I love the risk.

“If you don’t take risks in your life you never feel something new, so I taste something new and I like that. I don’t like to stay always with the easy life, so that’s why I took the risk and today I am very happy.”

Brazilian football expert Jack Lang wrote a piece on how Luiz has silenced his doubters this season:

Bielik out on loan?

Arsenal rumour now - with ESPN claiming that Krystian Bielik could be on his way out of the club again.

It would be a loan again, this time to Norwich City.

The young centre back was on loan at Birmingham City for the last portion of the 2016/17 season - and impressed Gianfranco Zola before he was sacked as Blues boss.

Perhaps another loan move could be best for Bielik, and promotion-chasing Norwich apparently think they could be the right club.

No Iheanacho for Spurs

It seems that Manchester City striker Kelechi Iheanacho could well be on his way out of the club this summer - but Spurs won’t be the destination.

That’s according to the player’s agent, who says that City won’t be selling the Nigerian to a title rival.

He told OwnGoalNigeria.com: “It’s clear he won’t be sold to a direct title rival by Man City, so when I see the reported interest from Spurs, I know if it becomes official it will be dismissed outrightly, but Everton and West Ham we will have to wait and see.”

Mourinho wants Morata

Now this could be very interesting...

Former Chelsea manager Jose Mourinho could be about to challenge the Blues for one of their top rumoured targets this window.

According to Spanish outlet Marca, the United boss is looking for both Alvaro Morata and £21 million if Real Madrid want to sign David De Gea this window.

I wonder what Antonio Conte will have to say about that...

Wilf new deal

So, as we brought you earlier, Wilfried Zaha has signed a new deal with Crystal Palace.

He’s snubbed any interest from Spurs to put pen to paper on a new five-year contract with the Eagles.
